Orlowskiy M. Orlovsky M.J. The productivity of sugar beets depending on the using of alternative organic manures and Crystalon in the Forest-steppe zone of Ukraine.

3. Thesis for a Candidate Degree in Agricultural Sciences in Speciality 06.01.09. - Plant Production. - Institute for Sugar Beet of the UAAS, Kyiv, 2009. The dissertation elucidates the results of researches about the regularities of formation of productivity and the quality of sugar beets' yield depending on top-dressing by Crystalon brown at the background of alternative, traditional organic ma-nures and mineral fertilizers in the area of sufficient moistening in the Forest-steppe zone of Ukraine. According to the results of researches the optimal rates and time of top-dressing by Cryristalon at the background of mineral fertilizers and the use of alternative organic manures in the form of by-products (straw of winter wheat) as basic one and afterharvest green manures such as white mustard have been set, which in its turn has positively influenced upon the size and the duration of functioning of assimilative leaf surface, quantitative composition of sugar, indexes of photosynthetic activity of crop stands and efficiency of the use of nutrient elements from fertilizers. These components of the technology have provided yield increase and a melio-ration of the technological quality of root crops. The economic and energetic expediency of top-dressing of sugar beets has been determined.
